OW series Generators

OW series MMM Universal wideband multi-frequency power supplies

MMM multi frequency power ultrasonic generators - OW type

MMM ultrasonic generators represent a brand new approach to sonic and ultrasonic power supplies. MMM technology merges state of the art DSP and power electronics to produce high-efficiency active power in wide-band sonic and ultrasonic vibrations.

MMM Universal wideband multi-frequency power supplies can replace all other types of constant- or sweeping-frequency generators for use with piezoelectric transducers, submersible transducers, bench-top cleaners and sonochemical reactors.

OW series MMM power supplies are supplied as open-frame modules for integration into your ultrasonic system. OW series generators offer much higher frequency resolution than the equivalent OF models, making them suitable for applications requiring precise frequency settings.

All MSG modular ultrasonic generators, MSG.X00.OW, utilize MMM technology and are constructed with an open-frame design intended for integration into ultrasonic systems providing appropriate housing and protection. OW series generators have much higher frequency resolution than OF series generators, making them suitable for applications requiring precise frequency settings. The MSG.X00.OW generators are intended mainly for application in ultrasonic cleaning tanks and systems.

Mastersonic generator modules (OW series) are designed for internal mounting in the control cabinets of ultrasonic systems. Such cabinets should be very well ventilated, protecting the generator module from excessive dust, moisture and harmful chemical agents. The installation and electrical connection of the generator must be performed by a qualified specialist in electronics who is experienced in power ultrasonic systems. MSG.X00.OW is designed as a component part for integration into ultrasonic systems, and so is not equipped with a power supply ON/OFF switch - this must be supplied and installed by you. Please read manuals for more information on all these power supplies.

OF series
Like the OW series, OF series MMM power supplies are supplied as open-frame modules for integration into your ultrasonic system. The OF is a basic, value-for-money ultrasonic generator for applications where precise frequency control is not required.
IX series
IX series generators are supplied complete with housing as an independent power supply for piezoelectric acoustic loads. They offer maximum versatility and control options (in effect all the functionality of both the OF and OW series generators plus many additional options) and are suitable for use by people without a background in high-power ultrasonics. This makes them ideal for challenging R&D projects, laboratory applications and scientific research.
